Embodiment
To make to have further understanding to the purpose of the present invention, construction, feature and its function, hereby coordinate embodiment detailed
It is described as follows.
Fig. 1 is a kind of flow diagram for scan method that one embodiment of the invention provides；Fig. 2 is another implementation of the present invention
A kind of flow diagram for scan method that example provides.
As shown in Figure 1, the embodiment of the present invention provides a kind of scan method, which is used for scanning means, the scanning
Device includes scan method, which includes：
Step S112, project on the first color of light to object to be scanned.
Step S114, scanning element is controlled to shoot object to be scanned when projecting on the first color of light to object to be scanned,
Obtain the first image.
Step S115, the current threedimensional model of object to be scanned is obtained according to the first image.
Step S116, the non-sweep test on object to be scanned is determined according to current threedimensional model.
Step S118, using on the second non-sweep test of color light projection to object to be scanned, return to step S112.
First color of light and the second color of light are different, wherein, the first color of light can be blue light, feux rouges, green light wherein it
One, the second color of light can be wherein another for blue light, feux rouges, green light, preferably, the first color of light is blue light, the second color of light
For feux rouges or green light.
Preferably, it can be included using the step on the second non-sweep test of color light projection to object to be scanned：In
With the non-sweep test of the second color marking on one image, the first reference picture is obtained；Using the first reference picture as projection pattern,
With using on non-sweep test to the object to be scanned in the second color light projection projection pattern.Further, on the first image
With the non-sweep test of the second color marking, the step of obtaining the first reference picture, can include：Delete to remove on the first image and do not sweep
Retouch the part outside part, and in, with the non-sweep test of the second color marking, obtaining the first reference picture on the first image.
Further, step S118 is included：With on the second non-sweep test of color light projection to object to be scanned, return to step
S112, until determining to obtain the complete three-dimensional model of object to be scanned.
Exemplary, project on the first color of light to object to be scanned, on projection the first color of light to object to be scanned
When control scanning element to shoot object to be scanned, obtain image P1, the current three-dimensional mould of object to be scanned obtained according to image P1
Type A1, the non-sweep test B1 on image P1 is determined according to current threedimensional model A1, using the second non-scanner section of color light projection
Divide B1 to object to be scanned；The first color of light is projected to object to be scanned, in the first color of light of projection to object to be scanned
Controlled scanning element to shoot object to be scanned when upper, and obtained image P2, the current three-dimensional of object to be scanned is obtained according to image P2
Model A2, the non-sweep test B2 on image P2 is determined according to current threedimensional model A2, is not scanned using the second color light projection
Part B2 is on object to be scanned；The first color of light is projected to object to be scanned, in the first color of light of projection to scanning object
Control scanning element to shoot object to be scanned when on body, obtain image P3, first three is worked as according to image P3 acquisitions object to be scanned
Dimension module A3, the non-sweep test B3 on image P3 is determined according to current threedimensional model A3, is not scanned with the second color light projection
Part B3 is on object to be scanned；... repeat, until obtaining the complete three-dimensional model of object to be scanned.
Further, step S112 is included：Projected in first time period on the first color of light to object to be scanned, step S118
Comprising：In second time period with the second non-sweep test of color light projection to object to be scanned.Exemplary, it is assumed that when first
Between section be 0.3s (second), second time period 0.6s, then on scanning means projection the first color of light of 0.3s to object to be scanned, really
After fixed non-sweep test B1, on the second non-sweep test B1 of color light projection 0.6s to object to be scanned, afterwards, to project 0.3s
On first color of light to object to be scanned, after determining non-sweep test B2, with the second non-sweep test B2 of color light projection 0.6s
On to object to be scanned, so repeat.In this way, due to scanning the first color of light used with projecting used in non-sweep test
The second color of light be that alternating expression is got, in this way, the limitation of people's reaction eye time, the picture that user watches is the first color
The picture of light embedded in the picture of the second color of light, so user watch object to be scanned it can be learnt that non-sweep test with
And sweep test.Further, step S118 is included：In with the non-sweep test of the second color marking, being obtained on the first image
First reference picture, in second time period using the first reference picture as projection pattern, to be projected using the second color light projection
On non-sweep test to object to be scanned in pattern.
It should be noted that above-mentioned determine whether that the complete three-dimensional model for obtaining object to be scanned can be user people
What work determines or scanning means determined.Preferably, when scanning means obtains current threedimensional model, Ke Yigen
Determine whether to obtain the complete three-dimensional model of object to be scanned according to current threedimensional model；Specifically, judge current threedimensional model
In whether there is non-sweep test, if non-sweep test is not present, determine to obtain the complete three-dimensional model of object to be scanned.Such as
Shown in Fig. 2, scan method may comprise steps of：
Step S212, project on the first color of light to object to be scanned.
Step S214, scanning element is controlled to shoot object to be scanned when projecting on the first color of light to object to be scanned,
Obtain the first image.
Step S215, the current threedimensional model of object to be scanned is obtained according to the first image.
Step S216, the non-sweep test on object to be scanned is determined according to current threedimensional model.
Step S218, using on the second non-sweep test of color light projection to object to be scanned.
Step S220, determined whether to obtain the complete three-dimensional model of object to be scanned according to current threedimensional model, if it is not,
Return to step S212, if so, terminating flow.
It should be noted that the above-mentioned current threedimensional model of basis determines whether to obtain the Complete three-dimensional mould of object to be scanned
As long as the step of type, is located at after step S215, for example, determining whether to obtain scanning object according to current threedimensional model
The step of complete three-dimensional model of body, is located at after step S215, then, if obtaining the complete three-dimensional model of object to be scanned,
Terminate flow, if not obtaining the complete three-dimensional model of object to be scanned, perform step S216, and after step S218, return
Step S212.
